MlTERlNG-MACHINE.

SPECIFICATION forifiiiig part of Letters Patent No. 629,425, dated July a5, 1899. Application filed May 28, 1898. Serial No. 682.056. (N model-J To all whom it 'nuty concern:

Be it known that I, GUsTAv CLEMENS, a subject of the Emperor of Germany, residing at Barmen, in the Province of Rhenish Prussia, Germany, have invented a new and valuable Improvement in lvlitering-lvlachines and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon.

Figure 1- of the drawings is a vertical section of the complete machine. Fig. 2 is a plan. Fig. 3 is a side view. Fig. ais afront view. Fig. 5 is a plan showing a modified arrangement of the machine.

The nature of my invention consists in a supporting clamp or abutment secured to the bed-plate of the machine in such a manner that it may be adjusted, together with the working piece, in horizontal and vertical direction and in such levels which may be combined of both directions.

ing by the nuts 0.

The invention further consists in-the sawguiding device, which is adjustable radially and in vertical direction, so that my improved mitering-machine is adjustable to admit any sized and shaped stick, molding, or board and any required miter, tenon, or tooth to be operated on.

The invention consists in the combination of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claims at the end of this specification.

Inthe accompanying drawings, a represents a rectangular or otherwise shaped base mounted on feet I) and attached to a suitable bench or table. To the front of this base is fixed a bearing 0, serving as a fulcrum for a fork d, which is turnably secured to the bear- The fork dis fitted with a horizontal bolt e, around which turns a clamp f, that serves as an abutment for the material being operated upon. In the present example the abutment consists of an angle-iron. It may be adjusted either in the horizontal plan, as shown in Fig. 2 by dotted lines, or in the vertical level, as illustrated in Fig. 1, or in an angle which may be combined of both levels, as shown in Fig. 3, so that all admitted miters may be adjusted. To secure the .abut mentfin any of the positions, Ihave arranged a slotted bar g, which rests upon the base a and is guided thereon by means of a slot it, cut into the base, so that it can follow the horizontal adjustment of the clamp f, the vertical adjustment being obtained by the slot 9. Screws it serve to fix the adjusted position of the clamp f, which may be fitted with a gage for the purpose of cutting the moldings to the proper length.

The saw is guided by slotted posts it, which may be radially turned, raised, and lowered to operate a more or less high work without respect to the self-movement of the saw-blade.

For this purpose I have fixed to the base two upright standards Z, on which may be moved up and down sockets m and fixed to the standards in any position by set-screws m. A round bar n, running across the base a, is fixed to the sockets m, carrying the posts it, which on said bar may be turned radially and raised or lowered, as shown in Fig. 3, in order to cut any tenon, tooth, and the like in any miter on the work. As shown in Fig. 5, I can i also turn the whole sawguiding device against the base a by separating both parts and arranging a vertical bolt 0, allowingthe turning of the guiding device.

The guide-post 7c is shown in Fig. l by a vertical section. It consists of the slotted tubular post it, in which is guided a hollow casing 1'. Two vertical rollers it are arranged rotatably therein, having collars s to receive and guide the saw-blade t, which by means of side strips t, passing between the rollers, engage the collars and force the casing r to move up and down within the tubular post 76.

To limit the downstroke of the saw-blade, I fix to the post it an adjustable set-angle 1), upon which the casing comes to rest in the adjusted lowest position.

Having now fully described my invention, I declare that what I claim is 1. In a mitering-machine the combination with a base,a gage adjustable horizontally and vertically or in any combination of these directions and means for securing the gage at movable in vertical direction 011 standards substantially as specified.

In testimony that I claim the foregoing as my invention I have hereto affixed my signa- I 5 ture in the presence of two subscribing Will: nesses.

GUSTAV CLEMENS.
